P50 Overheating

2016-05-22, 1:10 AM

Hello,

 

I just got a P50 in order to bring to college in the fall. Since I don't have any serious work to do, I've installed a few games to take advantage of the computer until then. However, I have noticed a problem. Playing Skyrim, one of my more intensive games, the computer gets very hot if placed flat on a hard surface such as a desk or table. The game has also crashed a few times when the computer has been on a flat surface and is very hot, which I believe may be due to throttling because of the heat. However, when propped up slightly to provide more clearance for the vents on the bottom, it stays much cooler and has not yet crashed my game. Is overheating normal for a laptop under heavy load like this? More specifically, is this behavior normal for the P50, or might I have a defective part?

 

Thanks!

Mine does not reach more than 85 degrees Celsius even under heavy load with prime/furmark.

It think I discovered my problem. Initially it crashed when I had it on my lap, which makes sense because my legs can mould to the underside and block vents, and are much warmer than the ambient temperature. Then I placed it on a tray, but I pushed it all the way back to make things more comfortable on my arm. The lip on the tray was probably blocking the rear vents which seem to be the exhaust so I think that was my problem.

 

I have both run a CPU stress test, and recreated the original circumstances with the computer flat on my desk, ensuring that the vents on the sides and back were clear, and both worked fine. So it's probably just my own stupidity rather than anything Lenovo did.

I've started to have the same issue on my P50, after the April 2018 Windows 10 update.  I can play a graphics game with the deadicated card for maybe 20-30 minutes and then the system abruptly powers off.

 

When I get rebooted, heat is around 115 degrees on the processor and graphics card.

If you haven't reapplied thermal paste since you acquired the machine, it may be time to do so.

I'm surprised there's a sudden need to replace the thermal paste on the heatsink/fan assembly on a laptop that's not 2-years old yet.  I suppose it's possible.

 

The HMM has guidence on removing the fan, though it's not really for the faint of heart.

https://download.lenovo.com/pccbbs/mobiles_pdf/p50_hmm_en_sp40j71944_03.pdf

 

There are 8 FRU removals before you get to the fan.  The guide cautions:

If you want to re-use the old thermal fan assembly, remove the thermal grease first, and then apply new thermal grease to the thermal fan assembly, at an amount of 0.2 grams, before you attach it to the system board. Either too much or too less application of grease can cause a thermal problem due to imperfect contact with a component.

 

 

Again, I'm surprised this is necessary on a laptop that's not really very old.

Any insight then on what direction we should go to find remedy? I agree, thermal paste shouldn't be an issue.
